Research Project: AREAWIDE PEST MANAGEMENT OF FRUIT FLIES IN HAWAII
2009 Annual Report


1a.Objectives (from AD-416)
To develop and integrate sustainable tephritid fruit fly management methods in areawide demonstration projects; to form long-term partnerships among federal, state, and the private sector. To transfer to growers economical and ecologically sound technologies to manage tephritid fruit flies on fruits and vegetables, and to enhance the export market. The objectives are to be met by the development and implementation of on-farm areawide pest management partnership demonstration sites in the Hawaiian Islands.


1b.Approach (from AD-416)
Through cooperation with stakeholders and with the help of University, state, federal, and private research agencies, we plan to demonstrate and implement the use of one or more of the following technologies to reduce populations of the four (4) species of fruit flies that attack agricultural crops..
1)Mass-trapping/male annihilation,.
2)bait sprays/bait stations,.
3)augmentative parasite releases, and.
4)sterile fly releases. Evaluation of the effectiveness of these technologies and cost-benefit analysis will be conducted to determine program success. Formerly 0500-00044-016-00D (2/05).


3.Progress Report
Direct ARS funding for the Hawaii AWPM program ended in FY-08. However, during FY-09 research on IPM of oriental fruit fly in papaya orchards was completed and documented. Two Specific Cooperative Agreements with the University of Hawaii will end in FY-09 and full reports will be included under these sub-projects. A third and fourth Specific Cooperative Agreement with Washington State University and ISCA technologies will end in FY-10. Progress reports are included under these sub-projects. A final report in the form of a brochure that highlights accomplishments, milestones and major references for the program was published in 2009 by the University of Hawaii and is included in the references section below.


4.Accomplishments
1. Suppression of fruit fly in Papaya Orchards using Bait sprays and field sanitation method. A major goal of the Hawaii Fruit Fly Area-Wide Pest Management (AWPM) Program is to suppress fruit flies below economic thresholds while integrating biologically-based pest technology into a comprehensive management package that is economically viable, environmentally sensitive and sustainable. Two major technologies being tested by ARS scientists in Hilo, HI include field sanitation and spinosad protein bait sprays. Since oriental fruit fly has proved to be the most difficult fruitfly species to control, the efficacy of FG-120 Naturalyte Fruit Fly Bait in combination with field sanitation was assessed as a control for female oriental fruit fly in papaya orchrards. Results suggested that foliar applications of GF-120 NF Naturalyte Fruit Fly Bait either to all rows (every other tree), or to every fifth row (every tree) in combination with good sanitation effectively reduces oriental fruit fly infestation in papaya orchards. Parasitism rates of fruit fly natural enemies were not affected. Papaya growers in Hawaii can benefit from the implementation of the two fruit fly management practices reported here because of the higher profits of papayas that are harvested riper due to the increase in quality of the product compared with the current practice of harvesting fruit at the mature green or color break stage.
